Define the RCDS data sets

To allocate your final RCDS data sets so that they can both be used by the ISPF interface and the server address space, you must follow the RCDS naming convention.

The naming convention for RCDS data sets is as follows:

DWWUSER.V610 - the value chosen as the RCDS prefix
DWWCON1 - DD name
GRP - constant
PROD - the value chosen as the group suffix

All active server address spaces in the sysplex that belong to the same XCF group can share one set of RCDS data sets. Only one server address space can be active per z/OS image. The RCDS data sets must be defined on DASD that is shared by all systems in a sysplex that belong to the same CICS VR XCF group.

This JCL example defines the RCDS data sets.

You can use the DWWRCDEF job to define RCDS data sets.
